Abstract
The utility model discloses a tensile permanent deformation test fixture of adjustable rubber, including the track bottom plate with set up accurate adjustment slider and the coarse adjusting slider on the track bottom plate, all be provided with the apron that is used for centre gripping rubber spare sample on accurate adjustment slider and coarse adjusting slider, pass adjusting screw behind the shoulder hole of backing plate the screw in and wear out the baffle, fix the backing plate outside the accurate adjustment slider, fix the baffle on the track bottom plate. The utility model has the advantages that: can be fast accurately with rubber spare sample drawing to 1.5 times of original distances to obtain accurate deflection. These anchor clamps can not only obtain experimental data (rubber deflection) accurately, can also improve the locating speed of experimental clamping, simultaneously can place a plurality of tensile permanent deformation test fixture of adjustable rubber and sample in the proof box, great improvement testing equipment's the rate of utilization, both improved test efficiency effectively, also practiced thrift a large amount of experimentation cost.
Description
Technical field
The utility model relates to high-speed railway fastener rubber mat plate and tests quick test fixture for rubber mat plate tensile set.
Background technology
China Express Railway uses the rubber mat plate in fastener system now, need the sample making Fig. 1 shape, need at the lines of a-quadrant inside-paint two at a distance of 25mm, then to stretch rubber with fixture, two lines at a distance of 25mm are moved to 1.5 times (i.e. 37.5mm) of original distance, then put ageing oven into and test, after ageing oven test, lay down fixture, record the spacing L of the gauge length line of former 25mm, thus draw tensile set rate.
Existing fixture structure is uncontrollable, is difficult to be stretched to original 1.5 times exactly during stretching, causes test findings error large, easily occurs dispute; And clamping speed is slow.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of adjustable rubber tensile scrag test fixture.
The technical solution of the utility model is: a kind of adjustable rubber tensile scrag test fixture, the accurate adjustment slide block comprising sole-plate and be arranged on sole-plate and coarse adjustment slide block, accurate adjustment slide block and coarse adjustment slide block are provided with the cover plate for clamping rubber parts sample, by adjusting screw(rod) through screwing in after the shoulder hole of backing plate and passing baffle plate, backing plate is fixed on outside accurate adjustment slide block, baffle plate is fixed on sole-plate.
Compared with prior art, the utility model has the advantages that: adopt this adjustable rubber tensile scrag test fixture, by the slide block be connected with the dovetail groove of two on sole-plate, moving slider is pulled to carry out coarse positioning to register pin by stayed mast, and then by adjusting screw(rod), accurate adjustment is carried out to slide block, to ensure rubber parts sample to be stretched to 1.5 times of original distances quickly and accurately, to obtain deflection accurately.This fixture accurately can not only obtain the data (rubber deformation amount) tested, and can also improve the locating speed of test clamping; Multiple adjustable rubber tensile scrag test fixture and sample can be placed simultaneously in chamber, improve the utilization rate of testing equipment greatly, both effectively improve test efficiency, also save a large amount of experimentation cost.
This adjustment rubber tensile scrag test fixture not only structure is simply beneficial to clamping but also accurate to testing the result that obtains, this utility model effectively utilizes screw thread clockwise and be rotated counterclockwise band movable slider and move left and right and to move left and right with track plates with slide block and can prevent the dovetail groove of front and back bob from coordinating, and reaches the effect of accurate adjustment rubber tensile length; Also on cover plate and slide block, add anti-slop serrations in addition, rubbery sample is effectively prevented after the stretch after adding anti-slop serrations, due to the screen resilience that the plastic yield of rubber produces, rubbery sample is slided between cover plate and slide block, so good warranty test obtains the true and reliable of data.This utility model reduces the error in test, thus ensure that the quality of product.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of rubber parts sample to be tensioned;
Fig. 2 is the front view of this adjustable rubber tensile scrag test fixture;
Fig. 3 is the vertical view of this adjustable rubber tensile scrag test fixture;
Fig. 4 is the connected mode of sole-plate and slide block.
Embodiment
A kind of adjustable rubber tensile scrag test fixture, as shown in Figures 2 and 3, comprise: sole-plate 1, register pin 2, moving slider (coarse adjustment slide block) 3, baffle plate 4, cross key grooved screw 5, handle 6, backing plate 7, band tooth cover plate 8, adjusting screw(rod) 9, moving slider (accurate adjustment slide block) 10, socket head cap screw 11, stayed mast 12 etc., wherein:
Sole-plate 1 is milled with a logical dovetail groove 13, and the dovetail mount arranged with accurate adjustment slide block 10 and coarse adjustment slide block 3 bottom surface coordinates (as shown in Figure 4), and accurate adjustment slide block 10 and coarse adjustment slide block 3 can be free to slide on sole-plate; Accurate adjustment slide block 10 and coarse adjustment slide block 3 are all provided with cover plate 8 by socket head cap screw 11, for clamping rubber parts sample; Clamping sample in order to more firm, not come off when pulling slide block, anti-slop serrations can be set on the surface of contact of cover plate and slide block.
By adjusting screw(rod) 9 through screwing in after the shoulder hole of backing plate 7 and passing baffle plate 4, then backing plate 7 is screwed in the outside of accurate adjustment slide block 10, one handle 6 is fixed at the end cross key grooved screw 5 of adjusting screw(rod), described baffle plate 4 is screwed on sole-plate 1, to ensure when turning handle, accurate adjustment slide block 10 is driven to move left and right by adjusting screw(rod).
By after rubber parts sample holder is on accurate adjustment slide block 10 and coarse adjustment slide block 3, on sole-plate 1, inside coarse adjustment slide block 3, (being left side in Fig. 2 and Fig. 3) 40 to 42mm place is provided with the register pin 2 coordinated with the interporal lacuna on sole-plate; Why being 40 to 42mm, is because sample is generally 82 to 85mm, and stretch the distance of 1.5 times, then need coarse adjustment slide block 3 to move 40 to 42mm.
Arrange stayed mast 12 in coarse adjustment slide block 3 both sides, when motive force bar 12 drives coarse adjustment slide block 3 to assigned address (namely outside register pin 2), upwardly register pin 2 makes coarse adjustment slide block 3 be fixed on outside register pin.
Principle of work: the sample two ends of finishing line are pressed in the upper locking of two slide blocks (3 and 10) respectively by socket head cap screw 11 band tooth cover plate 8, then stayed mast 12 is pulled to make coarse adjustment slide block 3 move to pin hole place, upwardly register pin 2 is located, then the handle 6 in adjusting bolt 9 is turned with hand, accurate adjustment slide block 10 is moved left and right, reach the distance that two lines that accurate adjustment finishes become original 1.5 times, test rear taking-up register pin 2, can original position be returned to, take out sample and can measure its deformation rate.
